Title
(EN) DEVICE FOR INDICATING AT LEAST ONE MAGNITUDE
(FR) DISPOSITIF INDICATEUR D'AU MOINS UNE GRANDEUR
Abstract
(EN)
The device for indicating at least one magnitude comprises a planet carrier (25) designed to be moved at a first given speed, a toothed ring (19) designed to be moved at a second given speed, a planet wheel (28) pivotably mounted on the planet carrier (25) and designed to cooperate with the ring (19), an indicating member for the first units (10) which is supported by the toothed ring and designed to follow a circular trajectory, the position of the indicating member for the first units on the circle indicating a first magnitude, and further comprises an indicating member for the second units (22) which is fixedly joined to the planet wheel (28), in an eccentric position thereof, so that it travels on a hypocycloidal trajectory or a deformed hypocycloidal trajectory in the reference system connected with the ring, the position of the indicating member for the second units (22) relative to the reference system connected with the ring (19) indicating a second magnitude.
(FR)
Le dispositif indicateur d'au moins une grandeur comporte un porte-satellite (25) agencé pour être entraîné à une première vitesse donnée, une couronne dentée (19) agencée pour être entraînée à une seconde vitesse donnée, une roue-satellite (28) montée pivotante sur le porte-satellite (25) est agencée pour coopérer avec la couronne (19), un organe indicateur des premières unités (10) porté par la couronne dentée et agencé pour suivre une trajectoire en forme de cercle, la position de l'organe indicateur des premières unités sur le cercle indiquant une première grandeur, et comporte en outre un organe indicateur des secondes unités (22) solidaire de la roue-satellite (28), en position excentrée de cette dernière, de sorte qu'il parcourt une trajectoire en forme d'hypocycloïde, ou d'hypocycloïde déformée, dans le référentiel lié à la couronne, la position de l'organe indicateur des secondes unités (22) relativement au référentiel lié à la couronne (19) indiquant une seconde grandeur.
